Moving in? Bring your tabs and notes from

The promise

Every tab has a way back.

So you can close freely. Nothing Larksail does on its own is final, and nothing you close is gone.

  1. 01

    Open

    Work with as many tabs as the task needs. Larksail quietly notes when each one was last used.

  2. 02

    Closed

    Close them yourself, or let tabs you haven’t touched in a while go on their own. Larksail tells you where they went.

  3. 03

    In the archive

    Every closed tab waits in the archive, by day, searchable by title or address.

  4. 04

    Back

    One click brings a tab back — or a whole window, or everything after a restart.

Inside Larksail

Everything you open, save and learn, in one place.

The tab manager, the bookmark library and the scratch notes you’ve been juggling, linked: a note knows its sources, and a saved page is never lost.

Try it: Save window, then Undo. Or switch to Open tabs, or another space.

One click saves the whole window.

Put every tab in a collection, then close the window with a clear head. Tabs you leave open go to sleep when you’re not using them, so your browser stays fast.

  • Lighter browser Tabs you haven’t touched in 30 minutes are suspended: they stay in the tab bar, give their memory back and reload when you click.
  • Spaces Keep work, side projects and that trip apart, nested if you like.
  • Tidies itself Tabs you haven’t used in a while move to the archive on their own. Time away from your computer doesn’t count.
  • Merge windows Five windows into one, in a click: all of them, or the ones you pick.
Collections Notes Declutter

Try it: pick a page, a view, Grid, or Page in the preview.

A library, not a graveyard.

Everything you’ve saved, in one list you can search as you type. Larksail brings back the ones you saved and forgot, and with Pro keeps a readable copy of each page.

  • Library Every saved tab across your spaces, by site, tag or age, with a preview beside the list.
  • Saved and forgotten Saved a month ago, never opened? Keep it, open it, or let it go.
  • Peek with Space Press Space on any saved tab to see its saved copy, note and tags without opening it.
  • Search inside pages Find a page by a sentence you remember from it. Pro

Before we go
💡

A Viva Viagem card covers the trams, the metro and the train to Sintra. Top it up at any station.

Try it: edit the text, tick a box, hover a linked page, open the other note.

Notes beside your tabs.

Write down what you learned while the pages are still open. Link a note to the pages it came from, tick off a checklist, plan the work on a board.

  • Blocks Headings, checklists, toggles, callouts and tables. Type / for any block.
  • Links that keep up Link a note or a saved page with [[. Rename it and every link follows.
  • Boards A kanban in any note. Due dates, labels, checklists on cards and a board in the top bar come with Pro.
  • Yours in Markdown Export every note as Markdown files (an Obsidian vault in one click) and import yours.

Why switch

Three tools. One extension.

Tab managers save tabs, bookmark libraries keep pages, note apps hold notes. Larksail does all three, and they work together: whatever you close is one search away, and a note knows where it came from.

And a lot more

Everything a heavy tab user asks for.

Don’t need something? Switch it off. It disappears from Larksail and stops running, and your data stays put. See every feature.

  • Declutter

    Every open tab on one screen. Pick by site, age or duplicates, then group, save or close them together, with Undo.

  • Command palette

    Find any tab, collection, saved page, note, bookmark or bit of history, and run any action.

  • Sticky notes and images

    Checklists and pasted images, right on the board next to the tabs they’re about.

  • Layouts

    Cards, a list, a speed dial or wide sections. With Pro, a table and a free-form dashboard too.

  • AI, if you want it

    Ask your library a question and get answers with sources, free on your computer or with your own key. The assistant and summaries come with Pro. Off until you turn it on.

  • Automatic backups

    A copy of everything (tabs, collections and notes) in your Downloads folder, on a schedule, with a health check.

  • Works with thousands of apps Pro

    Send what you save to Zapier, Make, n8n or your own server, and on to almost any app: a Slack message, a task, a row in a sheet. Off until you set one up.

    • Zapier
    • Make
    • n8n
    • Slack
    • Notion
    • Google Sheets
    • Todoist
    • Airtable
    • Gmail

Private by design

Your tabs say a lot about you. They stay with you.

Everything Larksail keeps lives in your browser, on your computer.

  • No account
  • No tracking
  • No ads
  • No uploads
  • No lock-in

Site access is asked for only when a feature needs it, with a word on why. Export everything, whenever you like.

Read the privacy policy

End-to-end encrypted sync

Sync, when you turn it on, is locked on your device before it leaves.

Keep your tabs and notes in step across your computers, without handing them to anyone. Sync is optional and comes with Pro.

How the encryption works
Locked on your device
Titles, addresses and notes are encrypted in your browser before anything is sent.
Unreadable to us
Our server only ever holds scrambled data. Not even we can open it.
Your key stays yours
Your recovery key is shown once and kept by you, never by us.
Off until you want it
Without sync, nothing leaves your computer at all.

FAQ

Questions

Something else? Write to us, or read why we made Larksail.

Is Larksail free?

Yes. Saving, collections, spaces, suspending, the archive, undo, snapshots, Declutter, the Library, notes with boards and tables, and every import and export are free, with no limits on collections, saved tabs or notes. Larksail Pro (coming) adds sync between your devices, readable copies of new pages and search inside them, the AI assistant and a few power features — the ones marked Pro on this page. Nothing free will ever get a cap.

Where is my data stored?

In your browser, on your computer. There is no account, and Larksail only goes online for features you turn on yourself, like AI with a provider you pick (or one running on your own computer). Uninstalling Larksail removes its data; backups you exported stay yours.

Can I take notes in Larksail?

Yes — a Notes page with a block editor: headings, checklists, tables, toggles, callouts and kanban boards, with [[links]] between notes and to your saved pages. Notes are in your backups, and you can export them all as Markdown (Obsidian opens the folder as a vault) or import yours.

Will Larksail sync between my computers?

Sync is coming with Larksail Pro, end-to-end encrypted: your collections, tabs and notes are locked on your device before they leave it, so not even we can read them. Until then everything stays on the computer it’s on — with automatic backups if you want a copy.

Will auto-archive close tabs I still need?

Auto-archive is off until you turn it on, and you choose how long a tab must sit unused (a week by default). Pinned, playing and grouped tabs are protected, time away from the computer doesn’t count, and every archived tab is one click from coming back.

How is Larksail different from OneTab, Toby, Raindrop or Notion?

Those tools each do one part: save tabs, keep bookmarks, or hold notes. Larksail does the three together — your tabs, a library of everything you saved, and notes linked to it — adds an archive of every closed tab and an undo for every automatic action, and keeps it all on your computer with no limits.

Which browsers does it work in?

Chrome, Firefox (140 or newer), Edge, Brave, Arc, Vivaldi, Opera and other Chromium browsers.

Can I bring my tabs from another tool?

Yes: Toby, OneTab, Session Buddy, Workona, Tab Session Manager, Pocket, Instapaper, Omnivore, Readwise Reader, Raindrop, Pinboard, any browser’s bookmarks, and plain lists of links. Notes, tags and save dates come along.

Why does it ask for access to all sites?

It doesn’t, at first. Larksail installs with no site access. If you turn on in-page undo notifications, saved copies or Focus mode, it asks then, and explains why. Saved copies read a page only when you save it, and keep the copy on your computer.

Does Larksail use AI?

Only if you want it. AI is off until you turn it on, and you choose where it runs: on your computer (Chrome’s built-in model or a local one like Ollama), or with your own Anthropic, OpenAI, Gemini or OpenRouter key. Larksail says exactly what it sends before anything leaves your computer.
